What is a Road Safety Audit?

A Road Safety Audit is an evaluation of a highway improvement scheme during design, at the end of construction and post-construction, to identify road safety problems and to suggest measures to eliminate or mitigate any concerns. Road Safety Audits are undertaken by teams of specialists trained in the skills of collision investigation and/or road safety engineering.

All strategic road schemes and the majority of new works are required to have an independent Road Safety Audit. Road Safety Audits aim to identify potential road safety hazards arising from planned changes to the road layout but they are not technical checks against design standards or traffic regulations.

In carrying out Road Safety Audits, the Audit team should consider road safety issues for all road users and will ask two key questions of the scheme

  • Who could be hurt in a collision on this part of the road and how could that happen?
  • What can be done to reduce the potential for that collision or to limit its consequences?

Road Safety Audits

Safety Audits are conducted in accordance with HD19/15 of the Design Manual for Roads and Bridges (Road Safety Audit)

Road Safety Audits go through four key phases and are as follows:-

Sometimes the Safety Audits can be combined; most often if the works are smaller in nature, or time scales are tight a Stage 1 & 2 Road Safety Audit maybe carried out together.

Some highway improvement schemes may not require Stage 4 Road Safety Audits unless the relevant authority request further collision monitoring/investigation.

The Road Safety Audit team members may be from the same company undertaking the Highway Improvement scheme design but have to be independent of any scheme design or process.

Road Safety Audits may be undertaken on highway schemes covering:

  • Major and minor highway improvements
  • Traffic management and calming schemes
  • Pedestrian and cycling schemes
  • Roundabout junctions
  • New or amended traffic signal junctions
  • Priority junctions
  • Motorway improvement

Non-Motorised User Audits

Government policy encourages consideration of the needs of non-motorised users and supports efforts to increase safety and accessibility by non-motorised modes.

The non-motorised user audit is defined as: A systematic process applied to Highway Schemes, by which the Design Team identifies scheme objectives for non-motorised users, documents the design decisions affecting non-motorised users, and reviews designs and construction to assess how well objectives have been achieved.

Non-motorised users are considered to be pedestrians, cyclists and equestrians. Non-motorised user audits require particular consideration to be given to the needs of disabled people, who may use any of these modes or other equipment such as wheelchairs.
